ASNR considers that the conclusions from the generic phase of the periodic safety review will pave the way for the continued operation of the 1,300 MWe reactors for the ten years following their fourth periodic safety review. ASNR considers that, alongside compliance with the requirements set out by ASNR, the measures planned by EDF will enable the objectives of the periodic safety review to be met, and will ensure that the safety level of the 1,300 MWe reactors is brought closer to the level achieved by the most recent reactors (third-generation reactors). As with the 900 MWe reactors, this will deliver the following notable outcomes : Verification on a large scale that the reactors comply with the applicable safety rules (see page 12) Limitation of the consequences of core meltdown accidents, in particular by reducing situations that would require the containment* to be depressurised, and by implementing measures to significantly reduce releases into the environment during this type of accident (see page 18) Improved consideration of the risks of hazards (such as flooding, explosion, fire, etc.,) and protection of the reactors against more severe natural hazards than those taken into account to date (see page 14) Limitation of the radiological consequences of accidents not involving core melt. This will make it possible to significantly reduce the occurrence of situations requiring measures to protect the general public to be taken (sheltering, evacuation, consumption of iodine tablets) (see page 20) Improved arrangements for managing accident situations in spent fuel pools (see page 16) Identification of improvements enabling each site to reduce its impact on the environment (see page 21) Conditions for the continued operation of 1,300 MWe reactors beyond 40 years • 11
